PURPOSE: A plate spring for an auto transmission of a vehicle is provided to prevent the bent part of the plate spring from being cut even if the plate spring is used for a long time by forming a flat surface in the bent part. CONSTITUTION: A plate spring(100) for an auto transmission of a vehicle comprises middle legs(103,104,105,106), a front end bent part(111), and middle bent parts(113,114,115). The middle legs are extended from front and rear end legs(101,102) and are formed in a zigzag shape. A first flat surface(111b) is formed in the front end bent part. Curved parts(113a,114a,115a) are formed in the centers of the middle bent parts. A pair of second flat surfaces(113b,114b,115b) are formed in the curved parts and are symmetrical to each other.
